Office Action

§102
Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . DETAILED ACTION Response to Arguments Applicants arguments and amendments, filed on 7/21/26, have been fully considered but they do not confer patentability on all of the instantly filed claims. The objection to the specification remains as the replacement compound D-1 is still missing a carbon-carbon double bond. The 112(b) rejection to claim 3 has been withdrawn as claim 3 has been canceled. Independent claim 1 has been amended to recite that L1 to L3 includes a substituted or unsubstituted C6 to C17 arylene group which is narrower than the C6 to C20 arylene group previously presented. Claim 1 has been further amended regarding variables Ar1 and Ar2 which are now limited to the Markush group as instantly claimed. Variables Ar1 and Ar2 no longer include triphenylene groups. Additionally, a triphenylene group is an aromatic group having 18 carbon atoms and no longer reads on any of variables L1 to L3. The prior art rejection to Kim et al. (US 2021/0098704) has been withdrawn. As can be seen in the abstract of Kim et al., the compounds of Chemical Formulae 1A and 1B are required to include a triphenylene group, which is presently excluded from claim 1. The prior art rejection to Jo et al. (US 2019/0348612) has been withdrawn. The compounds represented by Chemical Formula 1 of Kim et al. are required to include a triphenylene group, which is presently excluded from claim 1. Claim 14 has been amended to be an independent claim. Further search has led to a new prior art rejection as described below. Because this new prior art rejection rejects a claim which was previously indicated as containing allowable subject matter, this Office action is non-final. Specification Compound D-1 in paragraph 00269 of Applicants specification is missing a carbon-carbon bond. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claims 1-8, 10, 11, and 13-15 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Lui et al. (US 2020/0263357) as evidenced by a product data sheet from Lumora. Claim 1: Device example 2 of Lui et al. is drawn to an organic light-emitting device comprising a glass substrate, an anode (ITO), a hole injection layer (Compound A), a first hole transport layer (compound B), a second hole transport layer (compound C), a hole transport auxiliary layer (compound C-1), a light-emitting layer comprising a first host (compound 1-1), a second host (compound 1-62), a third host (compound 2-3), and a phosphorescent green dopant (PhGD), an electron transport and electron injection layer (Compound D and Liq), and a cathode (Al) (paragraphs 0375, 0383 and Table 2). Device example 3 anticipates all of the device limitations of claim 1. Compound C-1, which is the hole transport auxiliary layer, is N,N-di([1,1’-biphenyl]4-yl)-7,7-dimethyl-7H-fluoreno[4,3-b]benzofuran-10-amine (paragraph 0381). This compound has the structure PNG media_image1.png 230 308 media_image1.png Greyscale as evidenced by the product data sheet from Lumora, and referred to as DFBFA. The compound DFBFA satisfies the third compound represented by a combination of Chemical Formula 5 and Chemical Formula 6 of claim 1. As applied to the claimed third compound, DFBFA has L8-L10 equal to single bonds, Ar7 and Ar8 equal to biphenyl, X2 equal to CRcRd with Rc and Rd equal to methyl, m3 equal to 3 with all R24 equal to a hydrogen atom, b3* and b4* being joined to Chemical Formula 6, b1* and b2* being equal to C-Lb-Re with Lb equal to a single bond and Re equal to a hydrogen atom, X3 equal to O, m4 equal to 4, and all R25 equal to hydrogen atoms. The first host compound 1-1 has the structure PNG media_image2.png 154 208 media_image2.png Greyscale as taught on page 16. This compound anticipates Applicants claimed first compound of Chemical Formula 1. As applied to Chemical Formula 1, compound 1-1 has X1 equal to O, m1 equal to 4, R1 equal to hydrogen, m2 equal to 3, R3 equal to hydrogen, L3 equal to a single bond, Z1-Z3 equal to N, L1 and L2 equal to single bonds, Ar1 equal to an unsubstituted dibenzofuran group, and Ar2 equal to a substituted phenyl group (a diphenyl-substituted phenyl group). The third host compound 2-3 has the structure PNG media_image3.png 246 146 media_image3.png Greyscale as taught on page 35. This compound anticipates Applicants claimed second compound of Chemical Formula 2. As applied to Chemical Formula 2, compound 2-3 has n equal to zero, m9 and m10 equal to 3, R9 and R10 equal to hydrogen atoms, R5-R8, R11-R14 equal to hydrogen atoms, L4 and L5 equal to a single bond, and Ar3 and Ar4 equal to biphenylene. Claim 2: The first host compound 1-1 above also anticipates Chemical Formula 1-2 of claim 2, with all variable assignments being described above. Claim 4: The first host compound 1-1 above also anticipates Chemical Formula 1B of claim 3 with L1 equal to a single bond, X4 equal to O, m5 equal to 3, m6 equal to 4, all R26 and R27 equal to hydrogen atoms, and all other variables being described in claim 1 above. Claim 5: The first host compound 1-1 above also anticipates Chemical Formula 1B-1 with all variable assignments being described above. Claim 6: The second compound 2-3 above also anticipates Chemical Formula 2-8 of claim 6 with all variable assignments being described above. Claim 7: Compound DFBFA as shown in claim 1 above satisfies Chemical Formula 5E with the L groups equal to single bonds and Re3 and Re4 equal to hydrogen atoms, and all other variable assignments being described above in claim 1 above. Claim 8: Compound DFBFA satisfies claim 8 as described in claim 1 above. Claims 10 and 11: In compound DFBFA, Ar7 and Ar8 are either unsubstituted biphenyl groups, thereby satisfying claim 10 and the first structure shown in Group II of claim 11. Claim 13: Compound DFBFA as shown above is identical to compound D-51 of claim 13, thereby satisfying claim 13. Claim 15: The invention of Lui et al. includes preparing display devices (title, abstract, paragraphs 0002, 0013, and 0340 and claim 25) thereby anticipating claim 15. Allowable Subject Matter Claim 14 is allowed for reasons of record. Claims 9 and 12 are objected to as being dependent upon a rejected base claim, but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. The hole transport auxiliary compound C-1 as taught by Lui et al. above does not satisfy the structural limitations of claims 9 and 12.
